just polish your plenum!
thats what I meant. One from Z1 is like $500.
haha, i was there years and years ago in the barn when Russell was polishing his own by hand with a dremel
Have fun w/ that one. I think the one from Z gives you some extra HP on top of being polished
that Z is teh sex
Ya it is.
dont know about what you guys are talking about
polishing is easy.
just takes a while.
How would I go about doing it?
Polishing a honda valve cover is easy...
Polishing some SI wheels, kinda easy...
Polishing that Z32 intake plenum, not so easy
Ya it is like twice the size of a honda valve cover along with all the tight spots and curves and bullshit.
all you're really doing is sanding it. start w. a low grit like 100, then go to 240, 320, 400, 600, 800, 1000, 1500, then go to metal polish...
might be easier if you have a dremel
alot of work, pack of sandpaper is like $4, 8 diff. grits probably be around 35
Hmmm...Will probably try it next week for sure. Looks like im driving the truck for a few days.
yeah.
100- 220- 400- 800- 1000- 1500 then 2000 and polish.
Sounds like a plan to me.
you dont have to use 2000 on metal. thats what metal polish is for. you use it for cars just to skip the rubbing compound step. I just finished my fender and hit it w/ 2000 and went straight to the hi-speed polish.
It would be a hell of alot better and easier to use those bench grinders and attach some polishing discs and get some of them compounds. thats how people usually do their V8 valve covers in the custom shops
true.. i was wondering if i should have said 2000.
never polished an intake manifold before but i have polished floorboards on my old 74 VW beetle.
yeah...
to tell ya the truth, if you're using that bench grinder, you could probably stop after 600-800 w/ the sand paper. as long as the metal is smooth, the scratches will buff themselves out
